Eliminate frustrating creaks, prevent premature bearing wear, and ensure a flawless, press-fit installation every time by creating perfectly round and accurately sized bottom bracket shells.This tool is designed for accurately fitting milling of bottom bracket sleeves, correcting imperfections that can occur during frame manufacturing or after a new paint application. By machining the inner diameter of the shell, you guarantee that the bearings have a perfectly concentric and smooth surface to sit in, which is critical for optimal performance and longevity. The Park Tool 752 Reamer & Spacer Set 41.94mm provides everything needed to execute this crucial frame preparation task with confidence and unmatched accuracy.Specifically designed for the widespread BB30 standard, the 752 Reamer and Spacer Set allows reaming of bottom bracket frame shells to exacting tolerances. The precision-ground reamer is sized exactly at 41.94mm, the precise specification required for BB30 bearings to sit perfectly within the frame, ensuring a secure fit without binding or play.To operate, the 752 reamer is used with the versatile Park Tool HTR-1 Head Tube Reamer and Facer handle assembly and requires the 750.2 Centering Cone for perfect alignment within the shell (HTR-1 and 750.2 sold separately). This system ensures the reamer is guided smoothly and held perfectly concentric to the bottom bracket shell, resulting in a clean, precise cut from end to end. To prevent over-reaming and guarantee the correct depth, the set includes a dedicated spacer. This crucial component acts as a positive stop, ensuring you remove only the necessary material—typically just paint or minor metal imperfections—without altering the fundamental dimensions of the frame´s bottom bracket shell. This level of control is paramount for protecting the integrity of high-end carbon and alloy frames while achieving a perfect fit.
